To find the probability of an event we divide the No. of favorable outcomes of an event by Total no. of outcomes.

Or

Probability P(E) = No. of favorable outcomes of an event ÷ Total no. of Outcomes

Let's take an example for better understanding:

**Q- Suppose we throw a die once. What is the probability of getting a number greater than 4?**

Solve:

No. greater than 4 (favorable outcomes) = 2 *(5,6)*

Total no. (total outcomes) = 6 *(1,2,3,4,5,6)*

Probability P(E) = Favorable outcomes of an event ÷ Total Outcomes

P(E) = 2÷6

P(E) = 1/3
